FIELD OF THE INVENTION

[0001] The present invention relates to heat conductive device, and particularly to a method for forming a heat conductive device of superconductive metal block which comprises the steps of: placing at least one heat conductive superconductive tubes or containers and into a die-casting or casting mold; shaping heat conductive superconductive tubes or containers and melting metals into blocks by die-casting or casting mold so that the heat conductive superconductive tubes or containers are enclosed in the melting metals so as to be as an integral body.

BACKGROUND OF THE INVENTION

[0002] Currently, heat dissipating devices for low power CPUs or high heat sources are made by metal bases with metal fin sets so as to absorb heat and then dissipate heat by a fan.

[0003] This prior art way of using aluminum to make heat dissipating device is effective by low speed CPUs, but for CPUs with a high operation speed, a larger amount of heat can not be dissipated effectively. Thereby, copper is used to make heat dissipating device, which has a better heat conductivity. However, since the specific density of copper is 8.93 g/cm3 and aluminum is 2.7 g/cm3, to use copper as material for making heat dissipating device is too heavy to be accepted by user. Furthermore, copper is too heavy to pass through the experiment of collision and copper possibly causes the CPU to deform. Moreover, in practical use, copper is embedded into aluminum by forging and welding.

[0004] However, there are other materials which are more suitable for making heat dissipating device and other way, such as molding, can be used for making the heat dissipating device. Thereby, the present invention is desired to provide a method for solving the defect in the prior art.

[0005] Furthermore, in general design of the heat dissipating device to a CPU, a metal base is distant from the distal end of the fins, but only the base is in contact with the heat source (CPU). Thereby, the heat absorbed by the base can not be transferred to the distal end of the fins in short time. Moreover, the heat absorbed by the base is not identical to that in the fin. Thereby, only the roots of the fins near the base have the ability to dissipate heat effectively, but the distal ends of fins have only little effect in heat dissipation. Therefore, the above mentioned prior art can not match to the need of the high speed CPU capacity.

SUMMARY OF THE INVENTION

[0006] Accordingly, the primary object of the present invention is to provide a method for forming a heat conductive device of superconductive metal block comprising the steps of: placing at least one heat conductive superconductive tubes or containers and into a die-casting or casting mold; shaping heat conductive superconductive tubes or containers and melting metals into blocks by die-casting or casting mold so that the heat conductive superconductive tubes or containers are enclosed in the melting metals so as to be as an integral body.

[0007] Another object of the present invention is to provide a method for forming a heat conductive device of superconductive metal block, wherein the metal block is a high heat conductivity metal. The metal block is integrally formed with fins. The heat conductive superconductive tube is bent to have a helical shape. The heat conductive superconductive tube is bent as a U shape. The heat conductive superconductive tube is bent to have a three dimensional shape. There are a plurality of metal blocks which are stack packed one by one.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The method for forming a heat conductive superconductive metal block of the present invention will be described in the following.

[0017] Placing heat conductive superconductive tubes or containers and good heat conductive metal into a die-casting or casting mold.

[0018] Shaping heat conductive superconductive tubes or containers and melting metals into blocks by die-casting or casting mold so that the heat conductive superconductive tubes or containers are enclosed in the melting metals so as to be as an integral body, wherein the heat conductive superconductive tubes or containers are bendable metal tubes or containers, such as copper, aluminum, etc. The interior of the heat conductive superconductive tube or container is filled with high heat conductive materials, for example:

[0019] Inorganic high temperature super conductor compound, such as yttrium barium copper oxide (YBCO) super conductor material, thallium barium calcium copper oxide (TBCCO) super conductor material, mercury barium calcium copper oxide (HBCCO) super conductor material, bismuth strontium calcium copper oxide (BSCCO) super conductor material or other inorganic material.

[0020] One of the materials is organic material, such as water or other organ super conductor.

[0021] Other material can conduct heat with a high speed.

[0022] In the present invention, two sides of the tube or container are closed so that the heat conductor material therein will not drain out. Thereby, the heat conducting element is formed as a heat conduction super conductor tube or container.

[0023] If inorganic material is filled in the heat conductive superconductive tubes or containers, when heat is transferred to the tube or containers, the molecules therein will oscillate dramatically and rubber the wall of the tube or containers so that heat energy will transfer by mechanic waves.

[0024] When organ material is filled in the heat conductive superconductive tube or containers, the heat transfer is performed by heat convection. The heat transfer speed is very high. By experiment, it is shown that the speed of heat convention is five times of heat transfer speed in copper and over ten times of heat transfer speed in aluminum.

[0025] Referring to FIG. 1, the heat conductive superconductive tube 2 is bent to have a rectangular shape. Then melting metal 11 is molded as a rectangular tube so that the heat conductive superconductive tube is being enclosed in the melting metal so as to formed a heat conductive device of superconductive metal block. Thereby, when the metal block is in contact with heat source, heat can be transferred to the other end through the heat conductive superconductive tube 2 so as to improve the heat transfer efficiency of the heat conductive device of superconductive metal block.

[0026] As shown in FIG. 2, in the present invention, the metal 11 can be molded to have a flat shape. Then a part of the heat conductive superconductive tube 2 being enclosing in the metal 11 and another portion of the heat conductive superconductive tube is extended out of the metal 11 so that the heat conductive superconductive tube is connected to heat dissipating elements for heat conduction. In this embodiment, two ends of the heat conductive superconductive tube are exposed out.

[0027] Referring to FIG. 3, in this the embodiment, it is shown that the one end of both two ends of the heat conductive superconductive tube are exposed out from the metal 11.

[0028] Referring to FIG. 4, another embodiment of embodiment is illustrated. Two ends of the heat conductive superconductive tubes 2 are embedded into two metal 11, and the middle sections of the heat conductive superconductive tubes 2 are exposed.

[0029] Referring to FIG. 5, in this embodiment, the present invention has the similar structure as those in FIG. 4, while a plurality of fins are formed on a surface of each metal block so as for dissipating heat.

[0030] Referring to FIG. 6, the metal block 1 are made as a U shape, wherein a plurality of heat conductive superconductive tubes 2 are whole embedded in the metal 11.

[0031] Referring to FIGS. 7 and 8, the heat conductive superconductive tube 2 can be formed with a spiral shape and then the heat conductive superconductive tube 2 is placed in the metal 11 so as to formed with a first metal block 1. Then a CPU 4 is placed upon a second metal block 1. Then a dissipating fin set 3 is placed upon the first metal block 1 so that heat from the CPU 4 can be transferred out rapidly from the metal block 1 to the dissipating fin set 3.

[0032] Thereby, by the present invention, the metal block can be installed between a heat source and a dissipating fin set or a casing. Then a fan is installed at the side of the dissipating fin set or the casing for dissipating heat. Thereby, when the space is narrow so that it is difficult to be installed with a fan, the present invention can be used to improve this condition.

[0033] Moreover, in the present invention, the heat conductive superconductive tubes or container can be bent with other three dimensional shape so as to suit the requirement of the installing space and thus have a preferred effect with the metal block.

[0034] The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
